For general plant air, dew points of 2°c to 4°c are considered adequate, well within the range of refrigeration dryers.
Refrigeration type dryers use less energy and hence are lower in first and operating costs.
Desiccant dryers, heatless type, use 10 to 15% purge air for regeneration of desiccant i.E. 10 to 15% of compressor power [hp] is being used as energy operating costs for drying thereby increasing the capital costs in installing extra capacity of compressor.
The refrigeration type air dryer is a packaged self contained unit, fully automatic and produces a steady level of dewpoint. There is no regeneration cycle with complex valving, no periodic recharging of chemicals, oil in the air stream does not affect performance.
However, if applications requiring extra dryness of air and pressure dew point below 2°c are required only an adsorption dryer will do. Generally for instrumentation air or in outdoor applications an adsorption dryer is called for.
